"F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead."

ZFS is definitely not the best choice for flash - media, plus it's very resource-hungry on the host - side of things, too. ZFS is plenty useful on a server, and even on a desktop it could possibly be useful, but it is not suitable for use in embedded devices with limited resources or devices where you simply have no need for all of its features.
